综采工作面过断层液压支架倒架原因分析及控制技术研究

Reason analysis and control technology research on hydraulic support falling passing through fault in fully mechanized mining face

本文通过分析镇城底矿22212综采工作面回采时,由于断层影响出现的液压支架倒架现象,总结分析了造成综采工作面液压支架倒架的原因,同时根据22212综采工作面实际情况提出了控制液压支架倒架的技术,并成功地应用于该工作面,为过断层时综采工作面液压支架倒架的控制提供了借鉴。

By analyzing the phenomenon of hydraulic support falling due to the influence of fault in No.22212 Face of Zhenchengdi Mine,the causes of hydraulic support falling were summarized and analyzed.At the same time,according to the actual situation of No.22212 Face,the technology of controlling hydraulic support falling was put forward.This technology was successfully applied to this face,which provided a reference for the control of hydraulic support falling in fully mechanized mining face when passing through fault.
